These valves include a thread-in type, which comes in sizes from 5/16 to 7/16 inches, and a slip-in type in sizes from 1/8 to 3/8 inches. They are small enough to wipe out external leak points found with line-mounted check valves. Built for working with hydraulic fluid, they are made to go into manifolds, subplates, flanges and integrated hydraulic valve systems. Made out of steel, they provide positive fluid shutoff with hardened lapped discs and seats. Both types come with a sealing O-ring. Inserta Products Inc.http://rbi.ims.ca/4928-603
